+ The unicode update of test_server for R16A introduced a
+ few potential errors when logging to files. Sometimes ~tp
+ or ~ts was used for formatting also when writing to files
+ that were not opened with the {encoding,utf8} option. If
+ then the argument contained unicode characters above 255,
+ the file descriptor would crash. This has been corrected
+ by the following modifications: <list> <item> Since the
+ 'unexpected_io' log file is used only when the test case
+ HTML file is not available (e.g. between test cases),
+ this file is now also a HTML file and as other
+ test_server HTML logs it is always UTF-8 encoded </item>
+ <item> Since it is possible to change which information
+ is going to which log file (with
+ test_server_ctrl:set_levels/3), we do not have full
+ control over which information is written to which file.
+ This means that any printout could be written to the
+ 'major' log file (suite.log), which was earlier encoded
+ as latin1. To avoid crashing this file descriptor due to
+ unicode strings, the 'major' log file is now also encoded
+ in UTF-8 (possible incopatibility). </item> <item> The
+ cross_cover.info file is no longer a text file which can
+ be read with file:consult/1, instead it is written as a
+ pure binary file using term_to_binary when writing and
+ binary_to_term when reading. </item> <item> The encoding
+ of the file named 'last_name', which only content is the
+ path to the last run.&lt;timestamp&gt; directory, is now
+ dependent on the file name mode of the VM. If file names
+ are expected to be unicode, then the 'last_name' file is
+ UTF-8 encoded, else it is latin1 encoded. </item> </list></p>
+ <p>
+ Also, ~tp has been changed back to ~p unless it is
+ somehow likely that the argument includes strings. It is
+ not obvious that this is the correct thing to do, but
+ some decission had to be taken...</p>

+ <p>In test_server, the same process would supervise the
+ currently running test case and be group leader (and IO
+ server) for the test case. Furthermore, when running
+ parallel test cases, new temporary supervisor/group
+ leader processes were spawned and the process that was
+ group leader for sequential test cases would not be
+ active. That would lead to several problems:</p>
+ <p>* Processes started by init_per_suite will inherit the
+ group leader of the init_per_suite process (and that
+ group leader would not process IO requests when parallel
+ test cases was running). If later a parallel test case
+ caused such a processto print using (for example)
+ io:format/2, the calling would hang.</p>
+ <p>* Similarly, if a process was spawned from a parallel
+ test case, it would inherit the temporary group leader
+ for that parallel test case. If that spawned process
+ later - when the group of parallel tests have finished -
+ attempted to print something, its group leader would be
+ dead and there would be <c>badarg</c> exception.</p>
+ <p>Those problems have been solved by having group
+ leaders separate from the processes that supervises the
+ test cases, and keeping temporary group leader process
+ for parallel test cases alive until no more process in
+ the system use them as group leaders.</p>
+ <p>Also, a new <c>unexpected_io.log</c> log file
+ (reachable from the summary page of each test suite) has
+ been introduced. All unexpected IO will be printed into
+ it(for example, IO to a group leader for a parallel test
+ case that has finished).</p>

- A new option to erlang:system_monitor,
- {long_schedule,Millis} allows you to monitor if your
- system performs any lengthy NIF, BIF or driver operations
- that might result in bad resource utilization and
- therefore bad performance. To better test this
- functionality, the test_server has been updated to
- include configure tests for usleep.</p>
+ Added a general framework for executing benchmarks of
+ Erlang/OTP. Benchmarks for the Erlang VM and mnesia have
+ been incorporated in the framework. </p>
+ <p>
+ For details about how to add more benchmarks see
+ $ERL_TOP/HOWTO/BENCHMARKS.md in the source distribution.</p>

+ <item> Use UTF-8 encoding for all HTML files, except the
+ HTML version of the test suite generated with
+ erl2html2:convert, which will have the same encoding as
+ the original test suite (.erl) file. </item> <item>
+ Encode link targets in HTML files with
+ test_server_ctrl:uri_encode/1. </item> <item> Use unicode
+ modifier 't' with ~s when appropriate. </item> <item> Use
+ unicode:characters_to_list and
+ unicode:characters_to_binary for conversion between
+ binaries and strings instead of binary_to_list and
+ list_to_binary. </item> </list></p>
